GWS Digital Servos are all programmable and with the most advanced ASIC (Application Specific IC) IC to process the input signals, all with the best response time, and best resolution in 12+ bits or 4096+ steps. They work faster, more smoothly, more accurately.

These performance are much better than those another brands' digital servos which were with only MCU (micro controller) ones.
Those MCU ones are with lower response time, and lower resolution (10 bits or 1024 steps).
